Something is not right, the white luminance is much higher than 90
cd/m2, it's 121 cd/m2 (converting the Lab values back to XYZ).
Also the whitepoint is not even close to what the profile recorded.
Scaling XYZ to Y = 100, this gives me 101.5 100 114.8, but the profile
says 116.9 100 131.7. That's a delta E of almost 27.
